Here is info on the Patch pump, T:Sport
From tandem website.
t:sport Insulin Delivery System*
Our next-generation hardware platform is referred to under its development name, t:sport. Approximately half the size of our t:slim X2 pump, the t:sport pump is being designed for people who seek even greater discretion and flexibility with the use of their insulin pump. We anticipate that t:sport will feature a 200-unit cartridge, an on-pump bolus button, a rechargeable battery, an AID algorithm, and a Bluetooth radio. We anticipate that t:sport will be our first insulin pump to support full pump-control from our mobile application, subject to FDA review and approval.
